Description

Improved Mechanisms for Moving Dolls' Arms and Legs
(Addition to P 35 01 308.7 ________

In the main patent, mechanisms were claimed that noticeably improved the effect of the previously known mechanisms, which gives the movements of the arms and legs of the dolls an impression of realism that is one for children obvious attraction, as was the nature of the entire doll and the way it was connected the arms and legs of the same have been enhanced with the mechanism itself and the doll's body.

It has now been found that it is possible to use this mechanism to improve or perfect, alternately maintaining movements of the doll's legs, as if she would run, being at the same time for the body of the Doll serves as a frame and support, the outside of one Fabric and a foam filling is what the senses of the child is double the attraction as the movements are improved and more realistic and it feels softer and gentler.

The invention is explained in more detail below with reference to the drawing:

Fig. 1 is a top plan view of the improved mechanism according to this supplementary application.

Fig. 2 shows the same mechanism of Fig. 1 in side elevation and

Figure 3 shows a side view of the entire doll incorporating the improvements of the invention. In the drawing, a rigid housing 1 is shown in which the battery holder la in the rear part, the back of the Doll matches is included.

Inside this case there is a reduction gear 2, which consists of an electric micromotor that actuates a transmission reduction gear, which according to FIGS see the necessities to reduce the number of revolutions of the motor and increase its torque. This output shaft the reduction gear 2 protrudes on both sides and is at both ends with one Eccentric 3 connected, which are arranged in diametrically opposite position.

When turning the eccentric 3 and when they have entered the openings of the connecting rods 4, they give this one thrust in the longitudinal direction along the interior of the housing 1. The connecting rods 4 point at one of them Terminate a pin 5 which moves on the shaft and consequently maintains a rotary movement.

When the connecting rod 4 has its axis of rotation in FIG. 5a and the eccentric rotates, the connecting rod 4 moves with the End that is 5a opposite ^ from top to bottom and gives the grooved lever 6 a shock with its pin and lets it rotate on its shaft and gives the desired movement.

The grooved rod 6 is extended to the outside of the housing 1 by the end opposite its axis with a constricted section 6a and thus fulfills a safety function with regard to the possible breakage of the inner lever of the mechanism. Thereby this extension 6a is constricted and consists of a flexible and elastic material, the bending point of which is higher is as the resistance exerted by the walking or lower movement with respect to breaking any Part of the mechanism, a security with respect to the breakage of the doll becomes obtained when an external force is exerted on the legs which is higher than the one they withstand can.

At the 'lower end of the cord 6a is a grooved frustoconical extension connected in the Inside the legs / doll. These legs e have one on the front of the stump

Hole in which the said cone is housed both parts are secured in their connection by the grooves provided in the cones.

Inside the doll is a rotary switch with a counterweight housed, which opens the circuit depending on whether it is in an upright or lying position or closes.

When you raise the doll by holding its arms pulls, the switch is operated and the circuit completes, causing the activity of walking will. You have to hold on to her all the time you play with her because she cannot keep her balance.

If the doll falls or is laid down, it opens Rotary switch controls the circuit due to its counterweight and by the law of gravity and the mechanism comes to a standstill.

BOOO MUNICH BO date May 30, 1985 A 5835 Claims Ί 1. Improved mechanisms for the movement of the arms and Legs of dolls, characterized in that they are a a rigid case (1) comprising a battery holder in its rear part corresponding to the back of the doll (la) contains and in its interior a reduction gear (2), which consists of an electric micrometer, which actuates a transmission reduction gear, which reduces the revolutions of the motor and its torque according to the resulting needs increased. 2. Improved mechanisms according to claim 1, characterized characterized in that the output shaft of the reduction gear (2) protrudes on both sides and on their both ends are connected to an eccentric (3) each are arranged in a diametrically opposite position and in each of the openings of a connecting rod (4) have occurred, which they during their rotational movement in the longitudinal direction along the interior of the housing (D '- push, these connecting rods (4) are provided at one of their ends with a pin 5, which is on their Moves shaft and therefore maintains a rotary movement. 3. Improved mechanisms according to claim 1 and 2, characterized in that the connecting rods (4) are connected to their lower part with grooved rods (6), which they rotate on their ί ' Impart a wave that is desired for actuating the doll's arms and legs, these being grooved Rods at the end opposite their shaft and extended on the outside of the housing with a laced section made of flexible and elastic material, with the constrictions at the lower end a grooved frustoconical extension is connected which is housed in the interior of the legs (7) of the doll is made for this purpose in the anterior part of the stump 10 are provided with a perforation in which the cones are housed. 4. Improved mechanisms according to claims 1 to 3, characterized in that inside the doll a Rotary switch is housed with a counterweight that controls the circuit depending on whether it is in an upright position or lying position, opens or closes. 20th 25th 30th 35
